[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0040] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0041] According to the first aspect of this application, referring to Figure 1 and Figure 2 As shown, this disclosure provides a mining vehicle, including a frame, a powertrain 1, and a mounting structure 2.

[0042] In this embodiment, the mining vehicle can be a mining truck.

[0043] In some embodiments, continue to refer to Figure 2 As shown, the powertrain 1 includes a gearbox 15 with an output shaft 11, a flywheel cover 12, and a generator 13.

[0044] In this embodiment, the powertrain 1 outputs torque via the output shaft 11. The powertrain 1 also includes an engine 14, which is driven by a gearbox 15, a flywheel, and a generator 13. The gearbox 15 and the generator 13 are located on opposite sides of the engine 14.

[0045] According to the second aspect of this application, continued cooperation with reference to Figure 1As shown, this disclosure provides an installation structure 2 for the powertrain 1.

[0046] In this embodiment, the powertrain 1 is mounted to (e.g., bolted to) the vehicle frame via the mounting structure 2. The mounting structure 2 provides effective support for the powertrain 1.

[0047] In some embodiments, continue to refer to Figure 1 and Figure 2 As shown, the mounting structure 2 includes a main mounting component 21 and two auxiliary mounting components 22, which are connected to the vehicle frame.

[0048] In this embodiment, the main mounting member 21 and the auxiliary mounting member 22 are detachably connected (e.g., bolted) to the vehicle frame.

[0049] In some embodiments, the main mounting component 21 is connected to the powertrain 1.

[0050] In this embodiment, the main mounting component 21 is detachably connected (e.g., bolted) to the powertrain 1.

[0051] In some embodiments, in conjunction with reference Figure 3 As shown, two auxiliary mounting parts 22 are located on one side of the powertrain 1 along the first direction X, and the main mounting part 21 is located on the opposite side of the powertrain 1 along the first direction X.

[0052] In this embodiment, the powertrain 1 is installed (e.g., supported) along one side of the first direction X by the main mounting member 21, and the powertrain 1 is installed (e.g., supported) along the opposite side of the first direction X by two auxiliary mounting members 22, which can ensure that the powertrain 1 is stably installed (i.e., stably supported) along the opposite sides of the first direction X.

[0053] In some embodiments, two sub-mounts 22 are located on opposite sides of the powertrain 1 along the second direction Y.

[0054] In this embodiment, the two auxiliary mounting parts 22 are installed (e.g., supported) on opposite sides of the powertrain 1 along the second direction Y, which can ensure that the powertrain 1 (e.g. at the generator 13 and flywheel cover 12) is stably installed (i.e. stably supported) along both sides of the second direction Y.

[0055] In this embodiment, two auxiliary mounting members 22 and the main mounting member 21 are installed on opposite sides of the powertrain 1 along the first direction X, and two auxiliary mounting members 22 are installed on opposite sides of the powertrain 1 along the second direction Y. At this time, the two auxiliary mounting members 22 and the main mounting member 21 form a triangular arrangement. That is, the mounting structure 2 achieves a three-point installation (e.g., support) of the powertrain 1, realizing a balanced distribution of the load of the powertrain 1 on the mounting structure 2, improving the operational stability of the powertrain 1. Furthermore, it effectively avoids uneven stress at local mounting points, improves the reliability of the mounting structure 2, and extends the service life of both the powertrain 1 and the mounting structure 2. Therefore, it improves the operational stability and reliability of the powertrain 1 under complex and heavy-load conditions in mines, extends its service life, and meets the high reliability requirements of mining trucks for their power systems.

[0056] In this embodiment, the two auxiliary mounting components 22 and the main mounting component 21 are independently configured, allowing for weight and strength design tailored to different installation locations. This reduces the self-weight of the mounting structure 2 while ensuring overall rigidity and strength, thereby reducing the ineffective load on the mining vehicle and facilitating its lightweight design. The main and auxiliary mounting components 22 employ differentiated structural designs, optimizing the structure according to the forces acting at different locations, achieving lightweighting of the mounting structure 2 while ensuring sufficient strength.

[0057] In some embodiments, the first direction X intersects the second direction Y, and the first direction X is parallel to the axial direction of the output shaft 11.

[0058] In this embodiment, the first direction X is perpendicular to the second direction Y.

[0059] For example, the first direction X can be the forward / backward direction of the mining vehicle. The second direction Y can be the left / right direction of the mining vehicle.

[0060] In some embodiments, continue to refer to Figure 3 As shown, the auxiliary mounting component 22 includes a first mounting part 221 and a second mounting part 222, which are connected to the powertrain 1.

[0061] In this embodiment, the auxiliary mounting member 22 is connected to the powertrain 1 by the first mounting part 221 and the second mounting part 222, which increases the force transmission points between the auxiliary mounting member 22 and the powertrain 1 and avoids stress concentration on the auxiliary mounting member 22.

[0062] In this embodiment, the mounting structure 2 uses the main mounting component 21 and two auxiliary mounting components 22 to install the powertrain 1, and uses the first mounting part 221 and the second mounting part 222 of the auxiliary mounting component 22 to connect to the powertrain 1, which increases the force transmission points between the mounting structure 2 and the powertrain 1, avoids stress concentration, enables the mounting structure 2 to withstand the load of the powertrain 1, and increases the service life of the mounting structure 2.

[0063] In some embodiments, continue to refer to Figure 1 and Figure 2 As shown, the main mounting component 21 is connected to the gearbox 15, and the auxiliary mounting component 22 is connected to the flywheel cover 12 and the generator 13.

[0064] In this embodiment, the main mounting member 21 is detachably connected (e.g., bolted) to the gearbox 15, and the main mounting member 21 is capable of bearing the load on one side (e.g., the front side) of the gearbox 15 and the engine 14. The auxiliary mounting member 22 is detachably connected (e.g., bolted) to the flywheel cover 12 and the generator 13, and the two auxiliary mounting members 22 are capable of bearing the load on the other side (e.g., the rear side) of the generator 13 and the engine 14.

[0065] In some embodiments, continue to refer to Figure 3 As shown, the two sub-mounting components 22 are symmetrically arranged along the second direction Y.

[0066] In this embodiment, the two auxiliary mounting parts 22 are symmetrically arranged, which can improve the stability of the powertrain 1 (e.g., the flywheel cover 12 and generator 13 on the rear side) after installation, thereby improving the stability of the powertrain 1 during operation.

[0067] In some embodiments, such as Figure 3 The two auxiliary mounting components 22 can adopt a symmetrical structure. Compared with the solution where the two auxiliary mounting components 22 adopt the same structure, this solution has a better effect on improving the operational stability of the powertrain 1.

[0068] In other embodiments, the two sub-mounts 22 may have the same structure.

[0069] In some embodiments, in conjunction with reference Figure 3 and Figure 4 As shown, the first mounting part 221 and the second mounting part 222 are located on opposite sides of the sub-mount member 22 along the first direction X.

[0070] In this embodiment, the auxiliary mounting member 22 is connected to the flywheel cover 12 via the first mounting part 221 and to the generator 13 via the second mounting part 222. Since the flywheel cover 12 and the generator 13 are arranged along the first direction X, by placing the first mounting part 221 and the second mounting part 222 on opposite sides of the auxiliary mounting member 22 along the first direction X, the auxiliary mounting member 22 can be correspondingly connected to the flywheel cover 12 and the generator 13, thus meeting the installation requirements of the mounting structure 2.

[0071] In some embodiments, the first mounting portion 221 protrudes toward the powertrain 1 along a second direction Y relative to the second mounting portion 222.

[0072] In this embodiment, the distance between the first mounting portion 221 and the axis of the output shaft 11 is less than the distance between the second mounting portion 222 and the axis of the output shaft 11. That is, from Figure 4 Viewed from above, the first mounting part 221 and the second mounting part 222 are offset along the first direction X. This satisfies the different installation position requirements of the first mounting part 221 and the second mounting part 222, and meets the installation requirements of the auxiliary mounting part 22, making the mounting structure 2 (i.e., the auxiliary mounting part 22) fit more closely to the powertrain 1, thus saving the space occupied by the mounting structure 2.

[0073] For example, the first mounting part 221 is connected to the flywheel cover 12, and the second mounting part 222 is connected to the generator 13, which meets the different installation position requirements of the flywheel cover 12 and the generator 13. The mounting structure 2 (i.e., the auxiliary mounting part 22) fits into the flywheel cover 12 and the generator 13, saving the space occupied by the mounting structure 2.

[0074] In some embodiments, continue to refer to Figure 3 and Figure 4 As shown, the sub-mounting component 22 includes a first mounting plate 223, a second mounting plate 224, and a connecting plate 225 that connects the first mounting plate 223 and the second mounting plate 224.

[0075] For example, the first mounting plate 223, the second mounting plate 224 and the connecting plate 225 may be parallel to the vertical direction (e.g., the third direction Z), thereby improving the support strength of the sub-mount 22 for the powertrain 1.

[0076] In some embodiments, the first mounting plate 223 and the second mounting plate 224 are spaced apart along the second direction Y.

[0077] In this embodiment, the first mounting plate 223 and the second mounting plate 224 are spaced apart (e.g., parallel to each other), and the connecting plate 225 is connected between them. At this time, the connecting plate 225 is inclined relative to the two mounting plates, thereby improving the structural strength of the sub-mounting member 22.

[0078] In some embodiments, the first mounting part 221 is connected to the first mounting plate 223.

[0079] In this embodiment, the first mounting part 221 and the first mounting plate 223 can be connected in a non-removable manner. For example, the first mounting part 221 is welded to the first mounting plate 223, and the first mounting part 221 and the first mounting plate 223 are integrally formed (e.g., by casting or machining). This can improve the connection strength between the first mounting part 221 and the first mounting plate 223, thereby improving the overall strength and rigidity of the sub-mounting component 22.

[0080] In this embodiment, the first mounting part 221 and the first mounting plate 223 can be connected in a detachable manner, for example, the first mounting part 221 and the first mounting plate 223 can be connected by bolts, which facilitates the installation and removal of the first mounting part 221.

[0081] In some embodiments, the second mounting portion 222 is connected to the second mounting plate 224.

[0082] In this embodiment, the second mounting part 222 and the second mounting plate 224 can be connected in a non-removable manner. For example, the second mounting part 222 is welded to the second mounting plate 224, and the second mounting part 222 and the second mounting plate 224 are integrally formed (e.g., by casting or machining). This can improve the connection strength between the second mounting part 222 and the second mounting plate 224, thereby improving the overall strength and rigidity of the sub-mounted component 22.

[0083] In this embodiment, the second mounting part 222 and the second mounting plate 224 can be connected in a detachable manner, for example, the second mounting part 222 and the second mounting plate 224 can be connected by bolts, which facilitates the installation and removal of the second mounting part 222.

[0084] For example, the first mounting plate 223 and the second mounting plate 224 are spaced apart along the second direction Y, so that the first mounting part 221 and the second mounting part 222 are also spaced apart along the second direction Y after installation, satisfying the installation requirements of the first mounting part 221 and the second mounting part 222. The first mounting part 221 and the second mounting part 222 are located on different mounting plates (i.e., on different mounting planes), so that the two mounting plates and the connecting plate 225 fit more closely to the powertrain 1, saving the space occupied by the mounting structure 2 (i.e., the auxiliary mounting part 22).

[0085] For example, the first mounting part 221 is located between the first mounting plate 223 and the powertrain 1, and the second mounting part 222 is located between the second mounting plate 224 and the powertrain 1. That is, the two mounting plates are respectively connected to the powertrain 1 through the two mounting parts, which reduces the stress on the two mounting plates, avoids deformation and wear of the two mounting plates, and improves the service life of the two mounting plates.

[0086] For example, bolt holes 226 are provided on two mounting plates and two mounting portions, and the bolt holes 226 on the mounting plates and mounting portions are aligned axially. Thus, the first mounting portion 221 can be bolted to the flywheel cover 12, and the second mounting portion 222 can be bolted to the generator 13.

[0087] In some embodiments, in conjunction with reference Figure 3 , Figure 5 and Figure 6 As shown, the mounting structure 2 includes at least one mounting hole 23 and multiple vibration isolation elements 24.

[0088] In this embodiment, the mounting holes 23 can be used to bolt the structure 2 to the vehicle frame. The number of vibration dampers 24 can be twice the number of mounting holes 23.

[0089] In some embodiments, at least a portion of the vibration isolator 24 passes through the mounting hole 23.

[0090] In this embodiment, by passing the vibration isolator 24 through the mounting hole 23, at least a portion of the vibration isolator 24 is positioned between the bolt and the wall of the mounting hole 23 after the bolt passes through the mounting hole 23. The vibration isolator 24 is thus positioned and installed by passing through the mounting hole 23.

[0091] In some embodiments, mounting hole 23 is provided on main mounting member 21, and / or mounting hole 23 is provided on secondary mounting member 22.

[0092] In this embodiment, mounting holes 23 can be provided on both the main mounting member 21 and the auxiliary mounting member 22 to install corresponding vibration damping members 24. The mounting structure 2 is bolted to the vehicle frame through the mounting holes 23 on the main mounting member 21 and the auxiliary mounting member 22. Thus, the mounting structure 2 can effectively support and disperse the load of the powertrain 1 and attenuate vibrations using the vibration damping members 24 on the main mounting member 21 and the auxiliary mounting member 22, ensuring the stability and reliability of the engine 14 under harsh operating conditions. In the high-frequency vibration conditions of a mining environment, it effectively attenuates impact loads, preventing engine 14 vibrations from being directly transmitted to the vehicle frame, ensuring the smooth operation of the entire vehicle and the performance of the engine 14.

[0093] In some embodiments, the vibration isolator 24 abuts against the main mounting member 21 along the third direction Z.

[0094] In this embodiment, after the main mounting component 21 is bolted to the frame, the vibration isolation component 24 abuts against the main mounting component 21 along the third direction Z, which can effectively attenuate the vibration and impact load generated by the powertrain 1 during operation.

[0095] In some embodiments, the vibration isolator 24 abuts against the sub-mount 22 along the third direction Z.

[0096] In this embodiment, after the sub-mounting member 22 is bolted to the frame, the vibration isolator 24 abuts against the sub-mounting member 22 along the third direction Z, which can effectively attenuate the vibration and impact load generated by the powertrain 1 during operation.

[0097] In some embodiments, the first direction X, the second direction Y, and the third direction Z are mutually perpendicular.

[0098] In this embodiment, the third direction Z can be the vertical direction. Thus, the mounting structure 2 can provide vertical support for the powertrain 1 and can effectively attenuate the vibration and impact loads generated by the powertrain 1 during operation using the vibration isolation member 24, that is, attenuate the vibration and impact loads generated along the vertical direction.

[0099] In some embodiments, continue to refer to Figure 5 and Figure 6 As shown, the vibration isolation member 24 includes a mounting ring 241 and a vibration isolation ring 242, with the vibration isolation ring 242 sleeved on the mounting ring 241.

[0100] In this embodiment, the axis of the mounting ring 241 is parallel or collinear with the axis of the vibration isolation ring 242, which facilitates the vibration isolation component 24 to effectively isolate vibration after the mounting bolts are connected.

[0101] In some embodiments, the vibration isolation ring 242 is made of an elastic material.

[0102] In this embodiment, the vibration isolation ring 242 is made of elastic material, so that it elastically abuts against the main mounting part 21 and the auxiliary mounting part 22, thereby achieving the vibration isolation effect.

[0103] For example, the vibration isolation ring 242 can be made of rubber, such as nitrile rubber. The mounting ring 241 can be made of metal, such as 45# carbon steel, thereby enhancing the load-bearing capacity when the mounting ring 241 is inserted into the vibration isolation ring 242.

[0104] In this embodiment, the mounting ring 241 has a through hole at its center for bolts to pass through. The metal mounting ring 241 ensures the strength of the bolt connection. The vibration isolation ring 242 can be made of rubber, which can absorb and attenuate the vibrations and impacts generated by the operation of the powertrain 1. It can effectively prevent the frame from resonating and fully isolate the high-frequency vibrations and impact loads of the powertrain 1 during operation, thus greatly improving the operational stability of the powertrain 1 under harsh mining conditions.

[0105] In this embodiment, the vibration isolator 24 is made of high-strength steel and rubber, ensuring that the mining vehicle maintains excellent mechanical properties and durability under harsh mining environments such as high temperature, high humidity, and corrosiveness, meeting the requirements for long-term high-load operation of mining trucks. By using the high-strength steel and rubber composite vibration isolator 24, the load-bearing capacity and vibration isolation performance of the support system are improved.

[0106] For example, the main mounting component 21 and the auxiliary mounting component 22 can use the same or different vibration isolation components 24, respectively suitable for the load conditions at the front and rear ends of the powertrain 1, thereby effectively attenuating the vibration and impact loads of the engine 14 in the harsh mining environment and improving the overall operational stability. By configuring vibration isolation components 24 of different specifications and hardness at the front and rear ends, the deformation of each support point is coordinated and consistent, forming a more reliable vibration isolation scheme.

[0107] For example, the main mounting member 21 and the secondary mounting member 22 can employ different vibration damping elements 24. The main mounting member 21 uses relatively soft rubber to accommodate smaller loads at the front end. The secondary mounting member 22 uses relatively hard rubber to bear approximately two-thirds of the weight of the rear end of the powertrain 1.

[0108] In some embodiments, continue to refer to Figure 5 and Figure 6 As shown, the vibration isolation ring 242 includes a first ring 2421 that passes through the mounting hole 23 and a second ring 2422 connected to the first ring 2421.

[0109] In this embodiment, the second ring 2422 is located outside the mounting hole 23, thereby abutting against the main mounting member 21 or the auxiliary mounting member 22. The first ring 2421 abuts against the bolt, and the second ring 2422 abuts against the main mounting member 21 or the auxiliary mounting member 22 along the third direction Z. Thus, after the mounting structure 2 is bolted to the frame, the first ring 2421 and the second ring 2422 can isolate the high-frequency vibration between the two.

[0110] In some embodiments, the axis of the first ring 2421 is collinear with the axis of the second ring 2422, and the outer diameter of the first ring 2421 is smaller than the outer diameter of the second ring 2422.

[0111] In this embodiment, the vibration isolation ring 242 is composed of a first ring 2421 and a second ring 2422, forming a stepped structure, which enables the vibration isolation member 24 to be positioned and installed at the mounting hole 23, ensuring the installation accuracy of the vibration isolation member 24.

[0112] In some embodiments, continue to refer to Figure 5 and Figure 6 As shown, the installation structure 2 includes a first vibration isolation member 243, a second vibration isolation member 244, and at least one vibration isolation pad 25.

[0113] In this embodiment, the number of vibration isolation pads 25 may not be greater than the number of vibration isolation components 24. For example, the number of vibration isolation pads 25 may be half the number of vibration isolation components 24, or the number of vibration isolation pads 25 may correspond one-to-one with the number of vibration isolation components 24.

[0114] In some embodiments, the first vibration isolator 243 and the second vibration isolator 244 are disposed in the same mounting hole 23.

[0115] In this embodiment, the first vibration isolation member 243 and the second vibration isolation member 244 are installed in the same mounting hole 23, for example, symmetrically arranged, which can improve the vibration isolation effect.

[0116] In some embodiments, the first vibration isolator 243 and the second vibration isolator 244 are arranged symmetrically along the third direction Z.

[0117] In this embodiment, two vibration isolation members 24 are symmetrically inserted into the same mounting hole 23 to improve the vibration isolation effect along the third direction Z, that is, to improve the vibration in the vertical direction.

[0118] In this embodiment, the first vibration isolation member 243 and the second vibration isolation member 244 are simultaneously inserted through the mounting hole 23, so that they both abut against the bolt, which can improve the vibration isolation effect in the horizontal direction (i.e., perpendicular to the third direction Z).

[0119] In some embodiments, the vibration isolation pad 25 abuts against the side of the first vibration isolation member 243 and / or the second vibration isolation member 244 opposite to the mounting hole 23.

[0120] In this embodiment, the vibration damping pad 25 protects the vibration damper 24, for example, by preventing the bolt head or nut from squeezing and damaging the vibration damper 24. The vibration damping pad 25 also increases the contact area between the bolt and the vibration damper 24, thereby improving the vibration damping effect on the bolt.

[0121] For example, the vibration isolation pad 25 covers the vibration isolation member 24, that is, the outer diameter of the vibration isolation pad 25 is not less than the outer diameter of the second ring 2422.

[0122] For example, the first vibration isolator 243 has a vibration damping pad 25 on the side opposite to the mounting hole 23, meaning the first vibration isolator 243 contacts the bolt head or nut using the vibration damping pad 25. The second vibration isolator 244, however, contacts the vehicle frame directly and does not require a vibration damping pad 25. This forms a complete vibration reduction and force transmission path, and bolts pass through the vibration damping pad 25 and the vibration isolator 24 to prevent loosening during operation.

[0123] In some embodiments, continue to refer to Figure 5 As shown, the first vibration isolation member 243 and the second vibration isolation member 244 are spaced apart from each other along the third direction Z.

[0124] In this embodiment, the first vibration isolator 243 and the second vibration isolator 244 do not directly contact each other, which satisfies the vibration isolation requirements of the vibration isolator 24. For example, the main mounting component 21 is suitable for using relatively soft rubber hardness.

[0125] For example, the main mounting member 21 has a partition 211, which can be used to separate the first vibration isolation member 243 and the second vibration isolation member 244 by setting the partition 211 between them.

[0126] In some embodiments, continue to refer to Figure 6 As shown, the first vibration isolation member 243 and the second vibration isolation member 244 abut against each other along the third direction Z.

[0127] In this embodiment, the first vibration isolator 243 and the second vibration isolator 244 are in direct contact to meet the vibration isolation requirements of the vibration isolator 24. For example, the auxiliary mounting part 22 is suitable for using relatively hard rubber.

[0128] In this embodiment, the first vibration isolation member 243 and the second vibration isolation member 244 on the main mounting member 21 are spaced apart from each other, and the first vibration isolation member 243 and the second vibration isolation member 244 on the auxiliary mounting member 22 are in contact with each other, so as to meet the different vibration isolation requirements between the main mounting member 21 and the auxiliary mounting member 22, such as meeting the different loads borne by the main mounting member 21 and the auxiliary mounting member 22.

[0129] In some embodiments, continue to refer to Figure 6 As shown, the secondary mounting component 22 includes a secondary bearing plate 227 and at least one secondary vibration isolation pad 228.

[0130] In this embodiment, the secondary mounting component 22 may include one secondary vibration isolation pad 228. The secondary mounting component 22 may also include two secondary vibration isolation pads 228.

[0131] In some embodiments, the mounting hole 23 extends through the secondary bearing plate 227 and the secondary vibration isolation pad 228.

[0132] In this embodiment, the mounting hole 23 passes through the secondary bearing plate 227 and the secondary vibration isolation pad 228 along the third direction Z.

[0133] In some embodiments, the secondary vibration isolation pad 228 protrudes from at least one side of the secondary bearing plate 227 along the third direction Z.

[0134] In this embodiment, when the secondary mounting member 22 includes one secondary vibration isolation pad 228, the secondary vibration isolation pad 228 protrudes from one side of the secondary support plate 227 along the third direction Z. When the secondary mounting member 22 includes two secondary vibration isolation pads 228, one of the secondary vibration isolation pads 228 protrudes from the secondary support plate 227 along the third direction Z, and the other secondary vibration isolation pad 228 protrudes from the opposite side of the secondary support plate 227 along the third direction Z.

[0135] In this embodiment, the selection of the number of secondary vibration isolation pads 228 allows the secondary bearing plate 227 to meet the installation requirements of vibration isolation components 24 with different axial thicknesses. By setting the corresponding secondary vibration isolation pads 228, the vibration isolation requirements and the strength requirements of the bolt connection can be met. Moreover, the setting of secondary vibration isolation pads 228 can also strengthen the structure of the secondary mounting component 22, disperse the stress of the secondary mounting component 22, and achieve positioning and installation with the vibration isolation component 24.

[0136] For example, the secondary mounting component 22 includes a secondary vibration damping pad 228, which simplifies the structure. The secondary vibration damping pad 228 is disposed on the side of the secondary load-bearing plate 227 facing the vehicle frame. The secondary vibration damping pad 228 and the secondary load-bearing plate 227 can be separate or integrally formed.

[0137] For example, the secondary mounting member 22 is provided with two mounting holes 23, which are arranged along the first direction X. The two secondary mounting members 22 adopt a symmetrical structure, jointly bear the weight of the rear end of the engine 14 and the generator 13, and are connected to the vehicle frame through their respective two vibration isolation members 24 to maintain structural strength under variable load conditions.

[0138] For example, the secondary load-bearing plate 227 is connected to the bottom of the first mounting plate 223. Multiple reinforcing ribs 229 are connected between the secondary load-bearing plate 227 and the first mounting plate 223, which improves the structural strength of the secondary mounting component 22 and enhances its overall rigidity. The secondary mounting component 22 is provided with secondary lifting lugs 220 to facilitate the installation and hoisting of the powertrain 1. By rationally configuring the thickness of the two mounting plates and the secondary load-bearing plate 227, combined with the layout of the reinforcing ribs 229, and employing an integral welding process for the secondary mounting component 22, the self-weight of the secondary mounting component 22 is effectively reduced, the ineffective load on the mining vehicle is lowered, and the transportation efficiency of the mining vehicle is improved.

[0139] In some embodiments, continue to refer to Figure 5 As shown, the main mounting component 21 includes multiple main bearing plates 212 and at least one main vibration isolation pad 213.

[0140] In this embodiment, the main mounting component 21 may include one main vibration isolation pad 213. The main mounting component 21 may also include two main vibration isolation pads 213.

[0141] In some embodiments, the mounting hole 23 extends through the main support plate 212 and the main vibration isolation pad 213.

[0142] In this embodiment, the mounting hole 23 passes through the main bearing plate 212 and the main vibration isolation pad 213 along the third direction Z.

[0143] In some embodiments, the main vibration isolation pad 213 protrudes from at least one side of the main bearing plate 212 along the third direction Z.

[0144] In this embodiment, when the main mounting component 21 includes one main vibration isolation pad 213, the main vibration isolation pad 213 protrudes from one side of the main support plate 212 along the third direction Z. When the main mounting component 21 includes two main vibration isolation pads 213, one of the main vibration isolation pads 213 protrudes from the main support plate 212 along the third direction Z, and the other main vibration isolation pad 213 protrudes from the opposite side of the main support plate 212 along the third direction Z.

[0145] In this embodiment, the selection of the number of main vibration isolation pads 213 allows the main bearing plate 212 to meet the installation requirements of vibration isolation components 24 with different axial thicknesses. By setting the corresponding main vibration isolation pads 213, the vibration isolation requirements and the strength requirements of the bolt connection can be met. Moreover, the setting of the main vibration isolation pads 213 can also strengthen the structure of the main mounting component 21, disperse the stress of the main mounting component 21, and achieve positioning and installation with the main vibration component.

[0146] For example, the main mounting component 21 includes two main vibration isolation pads 213, which are disposed on opposite sides of the main support plate 212. The two main vibration isolation pads 213 form mounting holes 23, allowing the main support plate 212 to transmit force to the vibration isolation component 24 through the main vibration isolation pads 213. This improves the strength of the main support plate 212 while preventing deformation and damage. The main vibration isolation pads 213 and the main support plate 212 can be separate components or integrally formed.

[0147] For example, the main mounting member 21 is provided with two mounting holes 23, which are arranged along a first direction X.

[0148] In some embodiments, continue to refer to Figure 3 As shown, the main mounting component 21 includes a first main support plate 214, a second main support plate 215, a connecting part 216 connected to the powertrain 1, and a main body part 217 connected to the connecting part 216.

[0149] In this embodiment, the main body 217 is C-shaped, and its cross-section is I-shaped. The main body 217, the connecting part 216, and the two main load-bearing plates 212 are welded together to form an integral welded structure, which is connected to the vehicle frame through the vibration damper 24 to bear the load at the front end of the engine 14. The main body 217 is connected to the powertrain 1 via the connecting part 216 (e.g., bolted connection).

[0150] In this embodiment, the entire main mounting component 21 is welded into an integral structure to ensure structural strength under variable loads. The main body 217 is provided with a main lifting lug 218 for lifting, which facilitates the installation and maintenance of the powertrain 1. Ribs 219 are provided on both sides of the main body 217 along the first direction X, which can improve the overall structural rigidity of the main mounting component 21.

[0151] In some embodiments, the first main support plate 214 and the second main support plate 215 are connected to the main body portion 217 on the side opposite to the connecting portion 216 along the third direction Z.

[0152] In this embodiment, the main mounting component 21 connects to the powertrain 1 via the connecting part 216, and together with the two auxiliary mounting components 22, it installs (i.e. supports) the powertrain 1 at three locations, thereby improving the stability of the powertrain 1 after installation.

[0153] In some embodiments, the first main support plate 214 and the second main support plate 215 are located on opposite sides of the connecting portion 216 along the second direction Y.

[0154] In this embodiment, the main mounting component 21 connects with the vehicle frame using two opposing main load-bearing plates 212, and together with two auxiliary mounting components 22, so that the mounting structure 2 and the vehicle frame have four mounting points (i.e. four corner supports), which improves the stability of the powertrain 1 after installation.
